自2006年起的发亮可能是由于黑洞吸收了一个绕轨道而行的星星产生的风导致的，或者是由于一个气云盘旋进入了黑洞所致。

The brightening since 2006 could be caused by the black hole's capturing winds from an orbiting star, or by a gas cloud that spiraled into the black hole.

给星状的卫星潮汐的锁定情形相当未知，但是接近地-绕轨道而行二进被期望潮汐地被锁，连同，显然地，连络二进。

The tidal locking situation for asteroid moons is largely unknown , but closely - orbiting binaries are expected to be tidally locked , as well as , obviously , contact binaries.
